Let's reduce the confusion of HW
Having the ability to learn at your own pace, in your own time and in your own home makes a difference.
Close up videos of science experiments, crazy demonstrations are used along with vector graphics to make concepts easy to understand.
You don't have the time to ask questions in class or get detailed and highly visual answers many times in the busy time in class, BUT now you can with these videos and worksheets.
The courses cover 4 years of science content in the main areas of science (100's of videos) which are constantly being added improved and modified to improve worksheets, video questions / answers & subject content.
